STRIKING-MACHINE Specification of Letters Patent.

Patented Sept. 8, 1908.

Application filed July 20, 1907. Serial No. 384,771.

Be it known that we, RoYoE A. N OKES and WILLIAM W. GORDON, citizens of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Striking-Machines, of which the following is a specification. I

This invention relates to striking machines and particularly that class thereof wherein a person strikes upon a pivoted lever with a hammer or maul, which lever causes a block to ascend along a suitable support pro vided therefor, and over and opposite indicating numerals located at different heights whereby to indicate to the person the force of the blow struck by the hammer or maul.

Among the objects in view is to provide a machine of the character described which will be simple in construction, inexpensive, and efficient in operation.

Other objects and advantages will appear from the following description when taken in connection with the accompanying The invention consists in the novel conparts as hereinafter fully described,- illustrated in the drawings, and pointed out in the appended claims.

- In the drawings :Figure 1 is a front elevation of the improved striking machine. Fig. 2 is a side elevation of the machine. Fig.3 is a side elevation, partly in section, of the machine upon an enlarged scale. Fig. 4 is a detail perspective View of the pivoted lever and contiguous parts. Fig. 5 is a vertical sectional view on the line 5-5 of Fig. 3. Fig. 6 is a sectional view of a portion of the pivoted lever and its supporting base, and

lever. Fig. 7 is a vertical sectional view of porting base and other contiguous parts. Fig. 8 is a front elevation of the upper portion of Fig. 3, showing a slight modification.

9-9 of Fig.- 8. Fig. 10 is a, horizontal sectional view on line 1010 of Fig.8, Fig. 11 is a plan view of Fig. 8. Fig. 12-is a detail view, partly in section and partly in elevation, showing how two sections of the standard are connected together and also show-f indicators. Fig. 15 'is an elevation, partly in 'section, of the pin for striking the gong at the upper end of the standard. Fig. 16 is a detail erspective view of a portion of the stan ard, a'rod forming a la der rung, and the arms to which the upper ends of the Fig. 17 is a detail perspective view of a portion of the standardand the arms at the lower end thereof to which the lower ends of the wires secured.

The invention embodies a standard 1 which may be made either of wood or metal, preferably the latter, and we construct this standard of a series of sections adapted to be detachably secured together by any suit' able means, as for instance by sleeves or collars ,2, which are interiorly threaded to receive the threaded portions 3 of thesections 4 of the standard.

By the described construction we are en' abled to readily connect and disconnect the sectionsand may vary the height of the standard by simply adding one orjmore sections or removing same as will be readily understood. The standard is adapted to be firmly secured in upright position and any desired means may be used for this purpose. We show the lower section of the s'jtandard as being mounted in a block- 5;whi1cliina be res for the traveling blocks are secured} for the traveling blocks are of cement, stone, metalfoi wood'; w ich block is to be embedded'in the ground.

In order to firmly brace theistandard we employ a series of guy rods G'adapted to be connected at one end with the standard and,

at the opposite end to a suitablefixed sup"- port. We show, the upper ends of the guy rods as engaging with hooks 7 formed on rods 8 which are passed through openings 9 in the collars 2 while the lower ends of the guy rods are connected with turn buckles 10 into which screw threaded rods 11 which "hook into eyes 12 carried by suitable blocks 13 which areto be fixedly secured in position in any suitable manner.

.. By the described means the guy rods may uickly be tightened in order to firmly brace cure the upper ends of the guy rods to the -t e standard in position. We preferably secollars 2 at different heights which thus provides for still more firmly securing the standard in position. In connecting the rods S withthe collars 2, said rods, before having their ends bent, are passed through openings 9 in the collars, after which the ends of the rods are bent to form hooks 7.

We preferably provide the device with a suitable gong arranged at some point in the height of the standard, preferably at the upper end thereof, which is adapted to be struck directly by a block (or some movable part operated by the block) under the impulse imparted to said block, by one end of a pivoted lever, the opposite end of which is struck by a hammer or maul, and we preferably employ a gong 1-t which is suitably secured to an arm carried by a sleeve 16 which is mounted upon the uppermost section of the standard and detachably secured thereto by means of a set screw 17.

18 indicates the block which is adaptedto be driven upward by a person striking upon a suitably arranged lever, and this block is slidingly mounted. upon a wire 19 arranged in proximity to the standard and extending upwardly and firmly secured in position by any suitable means. \Ve construct the block of rubber and provide it with a cen tral metallic sleeve 20 to prevent the block from coming in. direct contact with the wire 19, which would cause excessive wear of the block when traveling up and down the wire. \V'e preferably secure the wire 19, attaching its upper end to a hook or stud 21 carried by an arm 22 which. is carried. by a sleeve 23.

mounted on the uppermost section of the standard, a rod 24 constituting a ladder rung and inserted through the section of the standard holding the sleeve .in its proper elevated position thereon. \Ye provide'each of the sections of the standard with one or more of the rods 24 for a purpose presently explainerh The lower end of the wire 19 has a hooked engagement with a threaded rod or bolt 25 which passes through an arm 26 carried by a sleeve 27 which is mounted on the lowermost section of the standard, and the lower end of the rod 25 being provided with an adjusting nut 28. 'lhus by adjusting the nut 28, the desired degree of tension may be put upon the wire 15) to hold it taut.

A rod or ladder rung 24 passed through the lowermost section of the standard holds the sleeve 27 in proper position. In order that the person may know the dill'crent degrees of force struck by the hammer or maul, we provide the apparatus with suitable indicatingmunbers arranged at dilfcrent heights along the standard and these numbers may be calculated to indicate the exactdegree of force or appr iximately. For thcstated purpose, we neferably employ indicators each comprising a plate 30 which are of metal,.

preferably tin, to which secured plates 31 provided with curved arms 32 adapted to partially embrace the sections of the standard. 'lhese arms' form a socket slightly more than a semi-circle in form and having sufficient spring to enable these arms to be sprung around thesections of the standard, the frictional engagement between the arms and the sections being sullicient to hold the indicators in whatever positions they have been placedon the standard.

The outer face of the plates 30 is provided with indicating numerals, 3U, which are painted or otherwis: applied to the indicators. .Ye preferably attach incandescent electric light bulbs 33 to the indicators, one

at each. end thereof, to which electric current is conducted by wires 3-1 from any suitable source, thus providing sullicient illumination at night to enable the person to see the indicating numerals.

\Yhile any suitable construction of pivoted lever may be employed, to be struck by the hammer or maul and to thereby drive the block 18 upwardly upon its supporting wire, we prefer to employ the construction of lever now to be described.

Upon a suitable supporting base. we mount a metallic bracket so between the arms 3Tflof' which we arrange a lever 38, preferably constructed of wood, said lever having bolted thereto upon oppositesidcs metallic plates 3.) provided with pivots or trunnions 10 which are pivotally supported in the arms 37. ()no end. of the lever is slotted as at 41 through which passes the wire 1.9 and upon the upper face of the slotted end of the lever, the block 18 is adapted to rest.. he opposite end of the lever 38 is adapted to rest upon a rubber block 42 which is mounted upon the upper end of a rod 4-3 passing upwardly through the base 35 and also through a wooden block 44 carried lltl bv said base, said block being held in posiupon the thremled end of the rod, and said rod being also provided with a collar 4c in-; sorted in a recess in, the block 14. '0 have found that in some. striking -machinos as heretofore constructed, it has been customary for the person to strike wit h the hammer or maul di-rcct-ly upon the pivoted lever but this results in frequent br akage of the .levcr as well as the hammer and to avoid this we provide a rubber blocl; -18 which is carried by the pivoted lever and which block 18 is adapted to directly receive the blows bf the hammer. o preferably attach the block 48 to the lever by means of a bolt 4!! which passes through the lever and a. perforation 50 in the block 48 and has a head .31 which lies within a recess 52 in the block 18.

When the block 4% is struck by a hammer end upon which rests the block 13 will be raised, thus causing the block 18 to be forcibly driven upwardly along the guide wire 19 and the highest point reached by the block 18 will be indicated by the numerals on the indicator opposite such highest point, and the block 18 will then descend and again rest upon the slotted end of the lever 38. For causing-the lever 38 to resume its normal position we employ a coil spring 55 arranged between the base and the outer end of the lever 38, said spring being confined in posiition by blocks 56 screwed to the base and ever.

In order to vary the degree of compressi-. bility of the block 42 so as to thereby vary thedegree of impulse given by the inner end of the lever 38 which would therefore affect the height to which the block 18would be driven, we employ suitable adjusting means for the lever 38 to cause the outer end of the lever to hear more or less forcibly upon the block 42, the preferred construction comprising a block 58 provided with pins or journals 59 which are pivoted in ears 60 secured to the upper face of the base 35, said block having a threaded aperture 61 in which screws a threaded rod 62 provided with a rod: 63 for enabling the rod to be readily turned by hand, the upper unthreaded portion of the rod fitting loosely within an aperture 64 in the lever 38.

A rubber block 65 is mounted on the unthreaded portion of the rod below the lever 38 to form a cushion for said lever when resuming its normal position after having been struck by a hammer.

the movement of the inner end of the lever By reason of providing a pivotal connection for the adjusting rod 62, the same can swing to permit of the proper movement of the lever 38. In order to strengthen the outer end of the lever 38 to prevent splitting or breakage thereof, we provide cleats or braces which are bolted to the lateral faces of the lever 38. I

In order that the gon 14 may be sounded when the block 18 is riven to its highest point, we provide a plunger 71 slidingly mounted in an openin 72 provided in the arm 22 at the upper en of the standard, this plunger being provided with a metal sleeve 73. The lower end of the plunger projects slightly'below the arm 22 in position to be struck by the block 18, and when struck, the

, sleeve 73 will strike against the gong. The

plunger 71 is preferably constructed of wood,

though it might be made of metal if desired,

and has a shoulder 74 adapted to normally rest upon the upper .faceof the arm 22.

It will be understood that by turning the rod 62 in the proper dito adapt the apparatus to be operated by say two persons simultaneously, we would provide an additional guide wire 78 and a block 18 adapted to'travel thereon and arrange a second striking lever 38 arranged similarly to the one first'described and adapted to operate the additional block 18 and would provide the additional arms 75 and 76 similar to the arms 22 and 26, and also provide the addi- I tional adjusting bolt'77 for putting the wire 78 under the proper tension. We also would provide the sleeve 16 with an additional arm to support an additional gong. WVe would say that we would prefer to employ the wire 78 and its tightening means, as well as its additional arms 75 and 76, even when the apparatus is to be used by one person at a time, since by so doing, the tension upon the wire 78 would counterbalance that upon the wire 19 to thus hold the parts in proper position. Should it befdesired to operate the apparatus by three or four 1- sons simultaneously, we simply add the additional striking levers and the additional blocks operated thereby and the supporting Wires forsaid blocks and also provide the required additional number of gongs.

In Figs. 8 and 11, we show four gongs 79- carried by arms 8.0 and provide a corresponding number of guide wires 81, the upper ends of which are engaged with lugs 82 carried by four arms 83, on a-sleeve 83 while the lower ends of the said wires are adapted to be engaged with tightening means 84, (Fig, 17) carried by four arms 85 projecting from the sleeve 86 mounted on the standard. Where the apparatusis to be operated byv two 'or more persons simultaneously, we arrange the indicators 87 in pairs so that one of said indicators will be upon one side of the standard, and'the other indicator upon the opposite side of said standard and these indicators are connected by means of plates 88 secured thereto said plates being connected by a socket portion 89 adapted to be sprung around the standard in the same manner as the socket seen in Figs. 13 and 14. Each of the indicators 87 carries two incandescent electric light bulbs 90 to provide sufficient light at night to illuminate the indicators.

The'rods24 hereinbefore described perform the function of ladder rungs, so that a person can readily mount the standard for the purpose of arranging the sections thereof in position or for any other desired purpose.
